Penglii Posted April 10, 2011 Author Report Share Posted April 10, 2011 (edited) Interesting development... the Tech-1 no longer works correctly hooked up to the TGP. It connects, and the Diagnostic Circuit Test works properly... but it always just says "waiting for data" if I try to do an idle relearn or get data readings or whatever. Gonna try to connect with TunerPro in a little while... if that connects OK then I'm not gonna be too worried I guess. But I wonder why it no longer works right. I'm gonna miss being able to relearn the idle so easily with the Tech-1... Edit: I should mention that I ran the engine for a few seconds to see if it would start. Started good, seemed to run... and the wideband was reading ~12.x All things considered this is a good start I think.

RobertISaar Posted April 10, 2011 Report Share Posted April 10, 2011 interesting indeed... then again, i've never done a scantool based idle learn. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted April 10, 2011 Report Share Posted April 10, 2011 Edit: I should mention that I ran the engine for a few seconds to see if it would start. Started good, seemed to run... and the wideband was reading ~12.x All things considered this is a good start I think. two questions now come up: was the SES or cooling fan on during this? if so, they would indicate that the ECM was operating in limp-home mode, in which case the ALDL stream would not be accessible. also: you did perma-wire JUST the A and M pins, yes? i can't remember which mode a 10K on B forces on a 7727 type ECM, but it would likely cause issues. good to hear it's running though.... just gotta wait for closed loop to kick in, since IIRC, that's when the issues start.

Penglii Posted April 10, 2011 Author Report Share Posted April 10, 2011 No SES or cooling fans running during any of the five ~30 second idling tests I have performed today. Yes I perma-wired wire A to pin A and wire M to pin M (assuming that the A wire is the one with the B wire branching off of it, I accidentally tore off the A & M labels. LOL) The other 2 (B, and I think it's E) have electrical tape over the tips. I feel like I should clip the wires and see if the Tech-1 will connect correctly again... but that's a depressing thing to do. It is definitely a relief that I still have a seemingly OK open loop idle... now i just got to play hide & seek with the data apparently.

Penglii Posted April 10, 2011 Author Report Share Posted April 10, 2011 Just swapped the tune for one that I know delivers data... datastream is still AWOL. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted April 10, 2011 Report Share Posted April 10, 2011 hmm... a permanently attached ALDL cable shouldn't be causing this, especially when i know you can hook up a cable behind the connector and log info from something like a Tech1 and grab all of it's commands as it sends them... are you flashing the chip in or out of the adapter? and yes, the A wire should have been a little bit shorter than the B wire(which is connected to the A wire via the 10K resistor).

Penglii Posted April 11, 2011 Author Report Share Posted April 11, 2011 Well then I hooked it up correctly... so that rules out that sort of fail. I am flashing the chip out of the adapter... using the Burn2. Since I keep forgetting to mail you your spare chip back, I was even able to check datastream existance with a chip that is known to provide one. It still did not work. So I'm fairly confident it's not the chip doing this. I suppose the only thing left for me to test is to clip the A & M wires and see if the Tech-1 gets a datastream again... although what comes next I don't know. The laptop recognized the USB adapter as a device and there was no indication of failure on the hardware end. Know of any fuses that might be relavent? The fact that the A & M pins still seem to ground fine for the diagnostic test yet the datastream is missing is particularly confusing. Hmmmmm.....

RobertISaar Posted April 11, 2011 Report Share Posted April 11, 2011 oh hell, i forgot you even had that one yeah, it is a bit odd.... if you do start clipping wires, clip M first, then see if it connects. if that works, then a toggle/rocker switch to allow the USB cable to connect and disconnect would work...

Although if the USB cable does not send a datastream to tunerpro currently, it might have to be a magical toggle switch to make things happen. I will clip the wires tomorrow after work and go from there... Quote Link to comment Share on other sites More sharing options...
Penglii Posted April 11, 2011 Author Report Share Posted April 11, 2011 Although if the USB cable does not send a datastream to tunerpro currently, it might have to be a magical toggle switch to make things happen. Well I suppose setting up Tunerpro correctly could very well help the USB end. So I might get lucky with the solution to this one. Then if I need to wire a toggle into the M wire, that will be a totally decent solution. Tomorrow is gonna be a long day while I wait to get home to check this possibility.

RobertISaar Posted April 11, 2011 Report Share Posted April 11, 2011 yeah, that would basically make a Laptop/Tech1 switch... Quote Link to comment Share on other sites More sharing options...
Penglii Posted April 12, 2011 Author Report Share Posted April 12, 2011 GOOD NEWS! I got the datastream to talk to Tunerpro, all that needed was the settings fiddled with. I also clipped the M wire and now the Tech-1 works again! So now I just gotta get a switch, and I should be able to get it wired in tomorrow. More good news... although I have not quite mastered Tunerpro's bizzare approach to creating/saving/managing log files, I was able to get a recording of a few minutes of idling. Long enough to get into closed loop. Which brings me to the next piece of good news... things did not immediately fall apart when entering closed loop! I have not done any idle relearn yet, so the data is not entirely useful yet, but I will post it anyway. I have yet to really examine it myself. AFR on the gauge was 14.xx most of the time. The Wideband is not wired directly into the ECM yet... it's presently just hooked up to emulate the narrowband, and providing AFR data through the gauge. Eventually I'll get the wiring harness modified... it does not seem too difficult... PengliiTGP_1st_log.xdl.zip Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted April 12, 2011 Report Share Posted April 12, 2011 bizarre? LOL, it's pretty simple to me(press one button to connect, another to record, another to stop, name log file, press save), then again, i've never needed to use another software package to deal with OBD1. definitely good to hear that it's not doing that crazy "imma enter closed loop now K? OHAI .1mS BPW, U LIEK?" i'll have to send you the patch for viewing the wideband through the ECM, if i haven't already. Quote Link to comment Share on other sites More sharing options...
Penglii Posted April 12, 2011 Author Report Share Posted April 12, 2011 Well OK when you put it that way it makes perfect sense... but initally I was confused. Dunno really why. LOL Ya... I no liek teh 0.1ms BPW I think I already have the patch... there are WB stats in the tunerpro log which I'm sure don't function right ATM, but if I wire the wire into the connector (I think I have instructions on that somewhere...) it should start giving WB data in the logs?

RobertISaar Posted April 12, 2011 Report Share Posted April 12, 2011 the wideband value shows up, but judging by the "9.18" value that shows up through the whole log, i'm going to say the patch hasn't been applied, since if it was, you would see ~7.35 with no sensor connected. since the patch basically overwrites the position in the ALDL stream that the TPS Volts was once at, i'd bet that the 9.18 is based on that(move the throttle with the engine off and you'll see the value change). you can change where the WB value gets placed, but that's just where someone initially put it (since TPS voltage isn't essential to tuning).

Penglii Posted April 12, 2011 Author Report Share Posted April 12, 2011 Gotcha... then I will need to get that from you sometime. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted April 12, 2011 Report Share Posted April 12, 2011 i actually have it integrated into the 8F XDF, if you have that. Quote Link to comment Share on other sites More sharing options...
Penglii Posted April 12, 2011 Author Report Share Posted April 12, 2011 Yes, I have that... how do I apply it? Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted April 12, 2011 Report Share Posted April 12, 2011 open up the scalars, scroll all the way to the bottom, and you'll see 5 values for the wideband, and when you mouse over them, it will tell you what to change them to. do that and viola, WB patch on pin C21.

RobertISaar Posted April 12, 2011 Report Share Posted April 12, 2011 just in case, here's the newest version of the 8F XDF... IIRC, i made a few changes related to the WB patch? 8F complete V1.05.zip Quote Link to comment Share on other sites More sharing options...
Garrett Powered Posted April 12, 2011 Report Share Posted April 12, 2011 Yes, I have that... how do I apply it? there is a button at the top of the screen in tunerpro. mouse over it and it will say select XDF. select 8F XDF. if that file is saved in My Documents in windows then you can click that to apply it to tunerpro. then there is another button to save it into tunerpro so its there each time you open the software. sorry if the explanation is the one robert described, that is how I interpreted your question, since I didn't have to select the wideband in the scalers. the innovate was the default for that XDF for me.

LOL that is just how to load the XDF into Tunerpro... but thanks for helping! It looks like I got the wideband patch applied and burned to the chip... now I just got to get it wired into the ECM harness... I'm going to try to get that done on Friday. Just gotta read up on how to get the connector apart and the pin installed. Tonight I will be wiring in the USB/ALDL switch and running an idle relearn Quote Link to comment Share on other sites More sharing options...
Penglii Posted April 12, 2011 Author Report Share Posted April 12, 2011 Just gotta read up on how to get the connector apart and the pin installed. So to double check... the wideband goes on pin C21 of the ECM harness? Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted April 12, 2011 Report Share Posted April 12, 2011 correct, it could be connected to other pins, though then the patch would need to be modified to do a A/D mux read instead of just a A/D read.. Quote Link to comment Share on other sites More sharing options...
Penglii Posted April 12, 2011 Author Report Share Posted April 12, 2011 Awesome. C21 works for me, maybe I'll do this tonight instead of the idle relearn. Since I'd have to re-do that anyway after adding the pin for the WB. LOL Quote Link to comment Share on other sites More sharing options...
